The Mayor of London is an elected politician who, along with the
London Assembly of 25 members, is accountable for the
strategic government of
Greater London. The current Mayor is
Sadiq Khan, who took up office on 9 May 2016. The position was held by
Ken Livingstone from the creation of the role on 4 May 2000, until he was defeated in May 2008 by
Boris Johnson, who served two terms before being succeeded by Khan.
The role, created in 2000 after the
London devolution referendum in 1998, was the first directly elected
mayor in the United Kingdom.
The Mayor of London directs the entirety of Greater London, including the
City of London, for which there is also the ceremonial
Lord Mayor of the City of London. Each
London Borough also has a ceremonial Mayor or, in
Tower Hamlets, an elected Mayor.
